Job Specifications

Full Stack Engineer | AI Startup | London

I am partnered with an AI startup backed by a significant fresh funding round looking to hire a full stack engineer to join a small, senior engineering team in London.

You’ll be working on production systems that build sophisticated workflow automations for an existing client base of leading names in the financial services sector. This is a hands on full stack role where you’ll work across frontend and backend systems, with enough backend depth to design and own APIs, services, and data flows, while also contributing to the frontend where needed.

What you’ll do

Design and build backend services and APIs in Python, typically using FastAPI or similar frameworks
Build and maintain frontend features using React and Next.js
Own data models, background workers, async processing, and system behaviour
Work with relational databases, caching layers, and task queues
Support CI CD, deployments, and cloud infrastructure in a practical, hands on way
Collaborate closely with other engineers to ship production features quickly and safely

How the stack looks in practice

Python for backend services and APIs
FastAPI or similar modern Python frameworks
React with Next.js on the frontend
Relational databases with Redis for caching and background jobs
Async processing and worker based architectures
Cloud infrastructure on Azure using managed services where appropriate

About you

Around 5 or more years of professional software engineering experience
Comfortable working across the stack with strong backend fundamentals
Experience building and operating production systems
Solid understanding of APIs, databases, and async processing
You care about reliability, maintainability, and sensible technical decisions
You are comfortable owning problems without heavy process or hand holding

Benefits

Competitive salary with significant equity upside
Opportunity to join at an early stage following a major funding round
High ownership and real technical influence
Direct access to senior technical leadership
Highly collaborative
Long term growth opportunities as the engineering team scales

If you are looking for a technically demanding full stack role where your work will have real impact, this is worth a conversation.
